A VPN or a virtual private network provides a private network across a public network, as we see with the Internet. The VPN enables a computer to send and receive data across shared networks or public networks as if it is directly connected to the private network, while it is benefiting from the functionality, security and management policies set for the private network. A VPN is created by establishing a virtual (PTP) point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryptions.
Through a (VPN) Virtual Private Network, you can access your private network over the Internet.
A (VPN) virtual private network connection across the Internet is similar to a (WAN) wide area network link between sites. From a user perspective, the extended network resources are accessed in the same way as resources available within the private network.
VPNs Virtual Private Networks allows employees to securely access their company’s intranet while traveling outside the office’s private network. Similarly, VPNs securely connect geographically different offices of an organization, creating one cohesive network as if it is all under one roof. VPN technology is also used by Internet users to connect to proxy servers for the purpose of protecting personal identity and location, by masking the ip with another ip or host name with another host name, and this again for the safety of maintaining privacy.
